Struct substrait_validator::input::proto::substrait::NamedStruct

pub struct NamedStruct {
    pub names: Vec<String>,
    pub struct: Option<Struct>,
}

A message for modeling name/type pairs.

Useful for representing relation schemas.

Notes:

• The names field is in depth-first order.

For example a schema such as:

a: int64 b: struct<c: float32, d: string>

would have a names field that looks like:

[“a”, “b”, “c”, “d”]

• Only struct fields are contained in this field’s elements,
• Map keys should be traversed first, then values when producing/consuming

Fields

names: Vec<String>

list of names in dfs order

struct: Option<Struct>

Trait Implementations

impl Clone for NamedStruct

fn clone(&self) -> NamedStruct

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NamedStruct

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NamedStruct

fn default() -> Self

Returns the “default value” for a type.

impl InputNode for NamedStruct

fn type_to_node() -> Node

Creates an empty output node for a protobuf datum of this type.

fn data_to_node(&self) -> Node

Creates an empty output node for a protobuf datum with this value.

fn oneof_variant(&self) -> Option<&'static str>

Returns the name of the selected variant of a oneof field, if this is a rust enum used to represent a oneof field.

fn parse_unknown(&self, y: &mut Context<'_>) -> bool

Complete the subtrees of this datum in output that have not already been parsed using UnknownField nodes. Returns whether any such nodes were added.

impl Message for NamedStruct

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: Buf,
    Self: Default, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<NamedStruct> for NamedStruct

fn eq(&self, other: &NamedStruct) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &NamedStruct) -> bool

This method tests for !=.

impl ProtoMessage for NamedStruct

fn proto_message_type() -> &'static str

Returns the protobuf type name for messages of this type.
